To find and view a Twitter account from the web, go to the search bar and type twitter/ user profile.  Here's an example: twitter/TweetEraser. Your search will open TwitterWeb and the user's profile page. From here, you can simply scroll down to view the user's most recent 3,200 tweets.

You will definitely ask this question: "How can I see anybody's Twitter Circle." Let's make it clear: You can't see anybody's Twitter Circle because it is a small and private audience group. And, do not worry, nobody can see your Twitter Circle. So, feel free to use Twitter Circle and add people to it.
